Chicago/Turabian Style Citation: Author-date Format
Many of you may be familiar with MLA and APA style citations. However, there is also a lesser know style of citation that you may be asked to use: Chicago/Turabian. This citation style varies substantially from MLA and APA style in that there are two systems, author-date or notes-bibliography, to reference sources. This handout will give you some basic information about the author-date format.
General Formatting for Either System Used (first page, heading, etc.)
- The title page should include the title of the paper, the writer’s name, the title of the course, the instructor’s name, and the date.
- Headings: Each page after the title page should include the writer’s last name and the page number in the upper right hand corner.
- Margins should be set at 1” on each side of the document.
- Block quotations are indented one tab (5 spaces) and double spaced. Omit quotations marks.
If you are familiar with MLA or APA style citations, this will look familiar, but there are differences. For in-text citation, please see the various in-text examples below. For your reference page, list sources in alphabetical order and format as follows:
